vb.org Archive - Disallow guests to view threads, must register first

I've been playing around with this hack and MAY have come up with a forumula to allow spiders to still view threads while denying permission to guest. I am not a coder by trade so please check this code out and see if it works for you. I've been running it about 3-4 hours and it seems spider friendly on my site.

There are three files to change and one file to upload.

archive/index.php
includes/functions.php
showthread.php

Upload this file and place in your forum root directory and the archive directory.
spiders.txt

Open archive/index.php and find:

Code:

$title .= ' - ' . $foruminfo['title'];

}

else

{

$do = 'index';

}

Below, add:

Code:

if (restrict_guest($bbuserinfo['userid']))

{

print_no_permission();

}

Open showthread.php and find:

Code:

globalize($_REQUEST, array('perpage' => INT, 'pagenumber', 'highlight'

=> STR, 'goto'));

Below, add:

Code:

if (restrict_guest($bbuserinfo['userid']))

{

print_no_permission();

}

In the same file find the lines:

Code:

if ($bbuserinfo['userid'] == 0 or $bbuserinfo['usergroupid'] == 3)

{

print_no_permission();

}

And replace them with:

Code:

if ($bbuserinfo['userid'] == 0 or $bbuserinfo['usergroupid'] == 3 and

!$spider_flag) 



{



print_no_permission();



}

In the same file find the lines:

Code:

if (!($forumperms & CANVIEWOTHERS) AND ($thread['postuserid'] !=

$bbuserinfo['userid'] OR $bbuserinfo['userid'] == 0)) {

print_no_permission();

}

And replace them with:

Code:

if (!($forumperms & CANVIEWOTHERS) AND ($thread['postuserid'] !=

$bbuserinfo['userid'] OR ($bbuserinfo['userid'] == 0 AND

!$spider_flag))) {

print_no_permission();

}

Open functions.php and at the end before

Code:

?>

Add:

Code:

function restrict_guest($user_id)

{



global $_SERVER, $spider_flag;



$user_agent = strtolower($_SERVER['HTTP_USER_AGENT']);



$spider_flag = false;



if ($user_agent != "")



{



$spiders = file('./spiders.txt');



for ($i=0, $n=sizeof($spiders); $i<$n; $i++)



{



if (!empty($spiders[$i]))



{



if (is_integer(strpos($user_agent,



trim($spiders[$i]))))



                                {



                                      $spider_flag = true;



                                       break;



                               }



                       }



               }



       }







       if ($user_id == 0 AND !$spider_flag)



       {



                return true;



        }



       return false;



}

DONE!
